This was a good attempt to simplify the already difficult task of key entry, but it was unsuccessful. It seems even more difficult to pull the key loop off and leave it open until you insert your key. To be honest, it doesn't spare your nails much. Also, it has a small ledge which I assume should help you open the key loop, which is nice but depends on how small the keyhole is for your key. It may not be possible to obtain a key to bypass the entire loop.
